Detection of Peronophythora litchii on lychee by loop-mediated isothermal amplification assay
Crop Protection, 2021Abstract Downy blight caused by Peronophythora litchii is one of the most destructive diseases of lychee (Litchi chinensis Sonn.). Early diagnosis of the P. litchii pathogen should be the top priority for addressing disease epidemics and management. In this study, loop-mediated isothermal amplification (LAMP) assays targeting the M90 gene sequences ...

Abstract Oomycete pathogens can secrete hundreds of effectors into plant cells to interfere with the plant immune system during infection. Here, we identified a Arg-X-Leu-Arg (RXLR) effector protein from the most destructive pathogen of litchi (Litchi chinensis Sonn.), Peronophythora litchii, and named it P.

Abstract Pectin is a major component of the primary cell wall of higher plants. Some galacturonyl residues in pectin are often O-acetylated. Pectin acetylesterases (PAEs) involved in enzymatic deacetylation of pectin are widespread in the plant pathogenic oomycetes and show sequence and transcriptional polymorphism. Peronophythora litchii is the most

Litchi downy blight, caused by Peronophythora litchi, decreases litchi production and fruit quality. The fungus infects litchi fruit through oospores developing into sporangia and zoospores being released by the sporangia in the litchi orchard. Our study investigated the biological characteristics of zoospore and oospore germination. If the germination

Arachidin-2 suppresses Peronophythora litchii and postharvest decay of litchi fruit
Food ChemistryLitchi downy blight, caused by Peronophythora litchii (P. litchii), is a devastating disease to litchi fruit. The objective of this study was to investigate the effects against P. litchii of arachidin-2 (ACD2), a naturally occurring secondary metabolite from peanuts.

Abstract Litchi is an important economic fruit in subtropical countries. The litchi downy blight (LDB) caused by the oomycete Peronophythora litchii severely affects the production and quality of litchi fruit, and is widespread in almost all litchi production regions of China.

Fungicide Effectiveness during the Various Developmental Stages of Peronophythora litchii In Vitro
Journal of Phytopathology, 2009AbstractLitchi downy blight caused by Peronophythora litchii is one of the most destructive diseases suffered by litchi in China. This study has evaluated the activities of the fungicides dimethomorph (DMM), azoxystrobin (AZB), famoxadone (FMD), metalaxyl (MTL), cymoxanil (CYX) and mancozeb (MCB) on the mycelial growth, sporulation, zoospores release ...

Sixty-eight field isolates of Peronophythora litchii, the causal agent of litchi downy blight, were examined for sensitivity to four novel QoI fungicides (SYP-1620, SYP-2815, ZJ0712 and enestroburin) in vitro with a mycelial growth assay. Ranges and means of EC50 values (in μg/mL) were 0.047–0.288 and 0.138 for SYP-2815, 0.056–0.992 and 0.148 for ...

Abstract Recent investigations have shown that disease development of harvested horticultural crops may be attributed to a limited availability of energy or low energy production. In this study, litchi fruit were treated with 1.0 mM adenosine triphosphate (ATP) or 0.5 mM 2,4-dinitrophenol (DNP) and then half of the ATP-treated fruit were inoculated ...
